Delhi air pollution: Supreme Court orders continuation of GRAP-4 in city for 3 more days

In a significant development, the Supreme Court of India has ordered the continuation of the Graded Response Action Plan (GRAP-4) in Delhi for at least three more days in a bid to combat the worsening air pollution levels in the national capital. The decision was made after the court reviewed the current environmental situation and the urgent need for stringent measures to curb the alarming levels of air pollution.

The GRAP-4, a set of emergency measures aimed at reducing pollution during severe air quality conditions, has been in effect in Delhi for the past few days. Under this plan, various restrictions are imposed, including the closure of construction sites, halting the operation of coal and biomass-based industries, and a ban on the use of diesel generator sets. In addition, the Delhi government has been advised to limit vehicular traffic, particularly diesel vehicles, and increase the deployment of machines to control dust.

Earlier, on Monday, the Delhi government imposed the restrictions under Stage 4 of the Graded Response Action Plan (GRAP-4) after the Air Quality Index (AQI) crossed 450 for the first time this season. The GRAP-4 restrictions cover a range of sectors, including the closure of physical classes and the ban on all construction activities. During GRAP-4 restriction period, the construction of all highways, roads, flyovers, power lines, pipelines and other public projects remained halted.
